Samplr For iPad.. it's like an OP-1!
With an interface designed for live performance, Samplr gives the musician quick and precise access to all the instrument functionality at any time.
Unlike other apps that try to recreate real life instruments or interaction concepts from traditional computers Samplr was designed for Multi-Touch devices from the very beginning.
5 sound effects, 6 simultaneous samples (with 6 voices each) and 7 different ways to interact with the sound. All modes are Multi-Touch ready.
